Alphabet cash flow turns negative as capex rises

What matters economically is not that Alphabet lacks the money to fund the buildout. It ended the quarter with $265.1 billion in cash and marketable securities, and trailing 12-month free cash flow remained positive at $19.7 billion. The issue is that AI infrastructure spending is rising faster than current cash generation, forcing investors to reassess how long the company can keep absorbing that investment without pressuring returns.

The spending binge is tied to data centers, servers and networking gear needed to support AI services, plus inventory for Alphabet’s custom Tensor Processing Unit systems. The quarter also included a $5.2 billion payment tied to a 2018 European Commission fine, which added another drag on cash flow.

At the same time, the operating business is still expanding at a pace most rivals would envy. Revenue rose 25% to $127.6 billion and operating income increased 30% to $40.6 billion, with margins improving to 32%. Google Cloud more than doubled revenue to $30.7 billion and tripled operating income to $11.1 billion, while Search revenue still climbed 12% to $63.4 billion.

That combination explains the market reaction: investors are not abandoning Alphabet because the core franchise is breaking, but because the payoff from AI spending is becoming harder to handicap. If cloud growth and AI services keep accelerating, the capex surge may prove justified. If not, the company risks tying up more cash in infrastructure while its most important advertising business faces longer-term pressure from generative AI.

For investors, the key questions now are whether Google Cloud can keep scaling profitably, whether Search can preserve ad monetization as AI changes query behavior, and whether free cash flow bottoms soon. Until Alphabet shows that the spending is translating into durable earnings and cash, the stock is likely to stay sensitive to every capex update.
